We have had some conversation within R core, lead by Duncan Murdoch and me, about a proposal to extend the current tracingState() functionality by something tentatively called debuggingState(). Duncan has allowed me to copy the previous conversation (after very minor editing): The following is quite technical and assumes you know more about R's debug()ing and trace()ing than an estimated 99.9% of the R users: >&gt...

trace() seems to be broken in 2.6.1 and R-devel: Try the example from the ?debug man page: > library(methods) > trace("plot", browser, exit=browser, signature = c("track", + "missing")) Error in getFunction(what, where = whereF) : no function "plot" found Okay, it's just an example that doesn't work. Let's try a simpler one,

Hi all, I know I shouldn't really expect the following to work, but it provokes a crash of the GUI on my computer (Win xp professional). --- >sessionInfo() Version 2.3.1 (2006-06-01) i386-pc-mingw32 attached base packages: [1] "methods" "stats" "graphics" "grDevices" "utils" "datasets" [7] "base"

Merry Xmas to all, I am writing a function and curiously this runs sometimes on one data set and fails on another and i cannot figure out why. Any help much appreciated. If i run the code below with data <- iris[ ,1:4] The code runs fine, but if i run on a large dataset i get the following error (showing data structures as matrix is large) > str(cluster.data) num [1:9985, 1:811] 0 0 0 0
